Adjusting the evaluation limits

The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply

voltage -U_B or +U_B to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s. LEDs

indicate whether the sensor has recognised the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught

with -U_B, A2 with +U_B.

Two different output functions can be set:

1. Analogue value increases with rising distance to object (rising ramp)

2. Analogue value falls with rising distance to object (falling ramp)

Evaluation limits may only be specified within the first 5 minutes after

Power on. To modify the evaluation limits later,

the user may specify the desired values only after a new Power On.

TEACH-IN rising ramp (A2 > A1)

- Position object at lower evaluation limit

- TEACH-IN lower limit A1 with - U_B

- Position object at upper evaluation limit

- TEACH-IN upper limit A2 with + U_B

TEACH-IN falling ramp (A1 > A2):

- Position object at lower evaluation limit

- TEACH-IN lower limit A2 with + U_B

- Position object at upper evaluation limit

- TEACH-IN upper limit A1 with - U_B

Default setting

A1: unusable area

A2: nominal sensing range

Mode of operation: rising ramp
